Materials, coefficients, notation

Materials, coefficients, notation

The following notation for material parameters is used:

fck

-

characteristic cube compressive strength of concrete

fcd

-

design strength of concrete in compression

fctk

-

characteristic strength of concrete in tension

fctd

-

design strength of concrete in tension

fy

-

characteristic strength of steel

fyd

-

design strength of steel in tension

The characteristic compressive strength of concrete is the basic input parameter given by the class of concrete – it serves to derive the remaining coefficients of reliability.

The most common notation for geometrical parameters:

b

-

cross-section width

h

-

cross-section depth

d

-

effective depth of cross-section

z

-

lever arm (arm of internal forces)

All computations are carried out according to the theory of limit states.
